STEREOPTICON LECTURES. 



During the past year a good stereopticon, or magic lantern, 

 has been secured, and is now used for illustrating insects and 

 methods of control before meetings of farmers, fruit growers, 

 etc. A considerable number of interesting lantern slides have 

 been obtained by purchase, while many others have been made 

 in our own laboratory at Baton Rouge, so that we now have 

 several hundred slides, from which selections can be made for 

 illustrating almost any phase of insect warfare. During the 

 past few months the entomologist and his assistants have given 

 stereopticon lectures at a number of towns, among them being 

 New Orleans, Calhoun, Lake Charles, ]\Iarksville and Marin- 

 gouin. It will be our policy from now on to furnish lecturer 

 and lantern free of charge to farmers' meetings and associations 

 anywhere in the State whenever requested to do so. 



CO-OPERATION WITH THE BUREAU OF ENTOMOLOGY. 



In accordance with the plans arranged at the beginning of 

 the fiscal year, July 1, 1906, the boll weevil investigation work 

 has been conducted in co-operation with the Bureau of Ento- 

 mology, Dr. L. 0. Howard and Dr. W. D. Hunter having as- 

 signed three Special Field Agents to duty in Louisiana in this 

 work, the salaries and traveling expenses of these field agents 

 being paid by the Bureau. 



Cultural experiments were conducted at Logansport, Batch- 

 elor and Willow Glen during 1906, the results of which are 

 given in Circular 11. Other experiments were conducted in 

 Vernon and Calcasieu Parishes to test the merits of a somewhat 

 generally established theory to the effect that late planting of 

 cotton would prevent damage by the boll weevil. The results 

 of these experiments, while negative, demonstrated the utter 

 impracticability of such a scheme. The full report on these 

 experiments,* as well as the report upon similar experiments 

 conducted by the Bureau of Entomology in Texas, t I have here 

 for your reference. 



*This report will shortly be printed and distributed to the parties upon the Com- 

 mission's miiilinti: list.
